Patient

Q: I am having a surgical prcedure on my uterus and the doctor put me on birth control pills to thin my uterus. this is the only time I will take birth conrol pills. It has been 15 years since I took birth control pills and I smoked last weekend at a party. I am a social smoker. I didn't think anything about it until I saw the insert this week that says DO NOT SMOKE while using this product.
